Specification of Letters Patent.

' Application filed March 29, 1916. Serial No. 87,897.

To all whom it may concern Be it known that I, FRANK citizen of the United States of siding in the borough of Brooklyn, city and State of New York, have invented a certain new and useful Improvement in Phonographs, of which the following is a specification.

My invention relates to an improvement in phonographs and is particularly directed toward the sound amplifying and controlling means, although other features of invention will become apparent as the description develops.

In the following I have described, in connection with the accompanying drawings, an embodiment of one wayof carrying out my invention, the features thereof being pointed out hereinafter in the claims.

In the drawings, Figure 1 is a top plan S. Moons, a

' view of the lower casing or body portion of a phonograph illustrating my invention, part being broken away;

Fig. 2 is a plan view from the inside of the top of the casing showing certain parts de tached from the body portion and housed in said top for transportation;

Fig. 3 is a side view partly in section and partly broken away, of the parts as shown in Fig. 1, the top being shown beneath to act as-a sound box; v

Fig. 4 is a sectional view of the casing assembled, with the phonograph parts removedto show the construction of the casing and showing also a means for storing records;

Fig. 5 is a perspective view of the body portion,- parts being removed, to show more clearly the arrangement of sound amplifying and directing means;

Fig. 6 is a perspective of the detachable sound director.

The device as illustrated is designed to be readily portable although the principles of the invention may as well be applied to those relatively more stationary.

In the drawings similar numerals of reference indicate similar parts.

1 indicates the lower casing or body portion of the phonograph and 2 the top or cover therefor, the two portions being adapted to be fitted pins 3 and corresponding recesses 4 and fas- America, re-- upon each other over doweltened together by any suitable means as by catches 5, 5. The body portion 1 may also be provided with recesses (not shown) in the bottom corresponding to recesses 4 so that when the top 2 has been emptied of the removable parts it may be placed beneath body portion 1 and used as a base therefor. In this position it also fulfils the function of an'alr'i'plifier.

The top 2 is preferably of suflicient depth to accommodate the removable parts as shown, the same being held against displacement therein by any suitable means as by spring clamps 6, 6, or if the removable parts are accommodated elsewhere, the top could be used for the storage of records.

The body portion 1 is preferably divided into two portions 7 and 8 by a transverse partition 9, the portion 7 being adapted to accommodate the motor mechanism 10 and the portion 8 being adapted to act as a sound reception box. 11 indicates a cover inclosing the body portion 1. One end of the body portion, as 12, is fastened to a portion of the cover 11, as 13, which in turn is hinged to the cover 11, so that when the same is swung upward, the sound reception box will be opened and the records 14, stored for safe keeping or for transportation in portion 8, may be removed. If the records should be stored in the top, portion 8 may be used for storage of the removable parts.

15 is a resilient device such as a leaf spring positioned on p'lartition 9, or elsewhere in the sound reception box in the path of arms or flaps, 16, 16 hinged together at 17 and adapted when in position in portion 8 to contact at the apex or hinged end with device or spring 15 and to have their other ends held in recesses or grooves 18 in the walls of casing 1 against which recesses they are urged by spring 15. The exact form of said part 16, 16 is not essential, thematerial feature of such detail being to form side walls for the sound box converging from without inwardly. In some instances part 16, 16 may be entirely omitted.

19 indicates an extension of the tone arm 20, provided with an opening 21 in the Wall thereof. Such extension may be either integral or separate from the tone arm but 1 have shown it as separate for convenience v of packing after demounting. 22 is a sleeve or clip around or partially around extension 19 and provided preferably with an opening 23 adapted to register with opening 21 in extension 19. Both extension 19 and sleeve 22 may be freely rotatable on their vertical axes, so that the sound through 'openlngs 21 and 23 may be directed to difl'erent parts of the sound reception box and, as extension 19 and sleeve 22 are also rotatable relatively to each other, the opening for the sound may be adjusted as desired. I prefer however to have extension 19 fixed in position. Sleeve 22 extends through cover 11 and is shown as provided with a flange 24 having a thumb piece 25 to assist in moving the same. Extension piece 19 also extends up through cover 11 within sleeve 22 and as shown, is adapted to receive tone-arm 20. Both extension 19 and sleeve 22 are removable from the body portion 1. Suitable indicating means, as shown, may be associated with the sleeve 22 to indicate the relative positions of; the openings through the extension piece and the sleeve; for instance, when the openings 21 and 23 register the volume of'sound from the tone-arm will be the loudest;

'27 indicates the reproducer and 28 the record support mounted on spindle 29 of the motor mechanism in any convenient way.

The operation of the device as illustrated is as follows: Assuming the removable parts to be housed in top 2, the records to be stored in portion 8 and the body portion 1 and top 2 to be fastened together like a small flat suit case; the catches 5, 5 will be released, top 2 removed from body portion 1 and laid to one side. End 12 will be lifted and turned back on cover 11 and the records 14: removed from portion 8. The removable parts will now be removed from top 2 and arms 16, 16 will be inserted into portion 8, hinged end 17 first, until end 17 contacts spring 15, when the arms 16, 16 having been spread out into contact with theside walls of portion 8, the free ends of the arms will snap into recesses or grooves 18. Sleeve 22 is next placed in position and extension 19 passed through sleeve 22. The tone-arm,

reproducer and other parts are-placed in po- .sition 1n the usual manner.

The motor bemg ready to operate, a record is placed in position and extension 19 and sleeve 22 adjusted relative to the size of opening therethrough and relative to the direction of the sound in the V-shaped amplifying chamber formed by the bottom and cover of body portlon 1 and the spread out arms 16, 16. The apparatus is then ready for .use. I prefer that the tone arm extension fit closely into the crotch of'the V-shaped walls with the opening 21 directed outward.

In demounting the reverse of the operation described takes place. It is preferred to make the case and the arms 16, 16 of wood. The emptied top 2 as descrlbed may be used as a base and sound box for body portion 1.- A handle (not shown) may be fastened to the case to assist in carrying the same.

It is obvious that certain of the parts may be varied in construction and arrangement without departing from thespirit of the 111- vention and I do not restrict myself further than the scope of the appended claims demands.

I claim: V
